摘要薏苡仁是我国传统的药食两用的保健食品，含有丰富的蛋白质、碳水化合物、脂类、矿物质以及灰分等成分，具有降压、降血糖和抗炎作用，性寒甘，利水健脾，正是大众所需求的“绿色食品”。但由于薏米的颗粒质地坚硬，正常蒸煮很难使其糊化，不易加工。本文以膨化薏米为原料，利用质构仪，采用单因素及正交分析方法，综合感官测定的结果，确定了膨化薏米酥性饼干的最佳配方为：（以薏米粉与面粉的总重量为100%）薏米粉12%、油脂25%、糖粉20%、疏松剂1.3%。以此最佳配方生产出的产品口感疏松适口，风纯正，品质优良。其中，油脂添加量对产品感官品质影响最大，其次是薏米粉的添加量、疏松剂的添加量和白砂糖添加量。37767

The Research and Development of Coix Seed Puffed Food
Abstract
Coix seed is Chinese traditional medicine and health food, it is rich in protein, carbohydrates, lipids, minerals, and the composition such as ash, antihypertensive, fall blood sugar and anti-inflammatory effects bitter in taste and cold-natured,invigorating spleen for diuresis, it is the popular demand of "green food". But as a result of coix seed particles hard, normal cooking is very difficult to make its gelatinization, not easy processing. Taking puffing coix seed as raw material, using the texture analyser, using the single factor and orthogonal analysis method, the comprehensive sensory determination results, identified the best prescription puffing of semen coicis crisp biscuit is: (to the total weight of coix seed powder and flour 100%) coix seed powder 12%, oil 25%, sugar 12%, loose agent 1.3%. To the best formula to produce a product texture osteoporosis sweetness that good flavor and high quality. Among them, the oil content had the greatest influence on product quality, the second is the coix seed powder to add quantity, bulking agent amount and the amount of sugar added.
